In this case, looking up the phrase "zerg rush" not only presents a page of search returns, but also a horde of low-powered letter "O"s from the Google logo, who begin attacking and systematically dismantling portions of the search returns page. Individual Zergian "O"s can be overcome by clicking on them, and both page elements and "O"s display health bars. Ultimately, any human player will be overcome, at which point the remaining "O"s will re-arrange into the letters GG, abbreviating "Good game!"
